I have some brand new 2014 Burton TWC Signature Pants up for sale here:
Burton Mens TWC 2014 Snowboard Black Denim Signature Pants Medium | eBay
I have not worn these except to try them on. I put on a little weight since I purchased them at the beginning of the season and didn't get a chance to wear them.
Auction Price is pretty cheap right now or 'Buy it Now' for $200...cheaper than retail.
